Autumn, 1937. Against the Imperial Army's objections, Lt. Colonel Yuuki
establishes the spy training group "D-Agency." The army sends Liuetenant Sakuma to serve as their liason to D-Agency, and he watches the applicants easily coast through the brutal examination process. Not long after, Sakuma is ordered by Colonel Mutou to search the home of a suspected American spy, the Japanophile John Gordon. Disguised as military police, Sakuma leads D-Agency on their first mission.
